INTRODUCTION Spacetime algebra is a Cliﬁord algebra representing the directional and. Groups and representations 30 §2. Elasticity theory is formulated in terms of a variety of variables including scalar, vector, and tensor fields, and this calls for the use of tensor notation along with tensor algebra and calculus. Those include its components, invariants, products (scalar products, compositions, tensor products and you already know the contraction with a vector which was the defining attribute.

The algorithm also may not converge to a local optimum, in that for a given distance metric it is possible that there exists alternative solutions within an infinitesimally small ε-ball of the converged solution with a better objective (see (Chen et al. Indeed, even if some aspects of tensor algebra can be considered as mature, several algebraic concepts such as decomposition uniqueness, rank. In a tensor world, a scalar is a 0-dimensional array, a vector is 1-d, and a 1 by 1, is a 2-d array.
